14 Claims.

It is among the general objects of the present invention to provide an efcient, coin controlled, automatic magazine talking machine which will be wholly automatic in its operation and which will accommodate a. large number of records in a single magazine from which they may be automatically selected for playing in a predetermined order or any one of which may be manually selected. r

Another object of the present invention is to improve and simplify the construction of such a machine to reduce its size and to provide positive means whereby its operation is rendered more reliable in the face of inexpert operation.

Othei objects of the present invention are the provision of improved selective record shifting means from the magazine to and from a turni table. improved means for automatically controlling the movement of the sound box so that it will properly cooperate with the record disc, and an electrical timing device to stop the other mechanisms while a record is playing.

One form of the invention which has 'been selected for purposes of illustration is shown in the drawings, of which Figure l is a rear elevation of an improved machine;

Fig. 16 isv an electrical wiring 'diagram of the 5 machine;

Fig. A1'7 is a section on the line I'l-I'I of Fig. 15 showing the clutch shifting mechanism.

The general framework of the .machine is enclosed in a suitable cabinet (not shown). The 10 framework comprisesv upper and lower substanftially rectangular cast metal frames 26 and 2i. Upon it are mounted or suspended the various mechanisms controlling the operation of the machine. The upper and lower frames are conl5 nected by* theupright posts 22, 23, 2t and 2t and the intermediate straps 26 and 21. Across the front and rear of the machine a pair of horizontal guide rails 2B are provided, which are fastened as indicated in Figs. .1 and 3.and pro- 20 vide additionalrigidity to the framework. The framework is mounted in the cabinet (not shown) preferably upon the lugs 29 secured to the side walls thereof.

A turn-table 30 is positioned on the right hand 25 i side (see Fig. 3) upon the upper end of a vertical shaft 3| driven by the usual phonograph motor 32 and having a governor 33 to regulate the speed. This may be of an approved type and is suitably geared with the vertical shaft 3l. The 30 turn-table shaft and its mechanism is spring suspended from a crossfplate 34 which in turn is fastened to a supplemental frame 35 rigidly mounted on the upright posts 24 and 25, and the intermediate straps 26 and 2l.

The disc records R are contained within a magazine M which can be automatically raised` and lowered so as to bring each of the records in the magazine into line with theturn-table 30 in a definite sequence.. Also it can be manually positioned so as to similarly position any one of the records in the magazine.y The magazine consists of a. rectangular framework 36 having a series of inwardly projecting arms 31 in sped relation to Aone another. The projecting arms 31 are disposed on opposite sides and have the disc plate 38 fastened at the points 39 as shown at Fig. 6. This disc plate 38 aids in forming a solid support for the records, insures against displacement due to a sudden jolt, and because of the perforations permits of the shifting ofrecords R, into playing position with little friction.

'I'he magazine framework 3B is mounted to slide upon a pair of guide rods 4| fixed at, their upper and lower ends to the metal frames and 2i rein the different adjusted positions.

spectively. A pair of anti-friction rollers` 42 at the upper ends of framework 86 engage the outer side of the guide rods 4| and a pair of anti-friction rollers 48 on the lower ends of framework 96 engage the inner sides of such rods'. Cord v44 attached to an inwardly extending lug 45 on the top of framework 86 is fastened to agrooved pulley 46 journalled in the uprights 41 on the top metal frame 28. A spiral cam 48 formed integral with the grooved pulley 46 and a retaining plate 49 fastened at its side has a cord 58 attached to it whichextends downwardlyr to the upper end of a heavyspring 5|. The lower end of the spring 5| is connected to the lower frame 2|. The purpose of the spring 5| is to partially counter-balance the weight of the magazine with the records therein and because of the spiral cam 48 spring 5| exerts an almost uniform pull on the magazine To further aid in counter-balancing the magazine a weight 52 is suspended from the upper portion of the framework 36 so as to slide within guide tube 53 mounted on the frame 2|.

Since all disc records are provided with the usual center openings a pair of xed vertical rods 54 and 55 are used to prevent displacement of the records R from the magazine. .The upper vertical rod 54 is detachably fixed to a cross-piece 56 on the frame 28 with the set-screw 51. A ring 58 attached to rod 54 is provided to remove this centering means so that the disc records can be changed as desired. 'I'he lowermost rod 55 is securely fixed to a bracket support 59 mounted on Ythe lower metal frame 2|. Referring to Figs. 2, 3

and 15 it will be noted that the adjacent ends of the rods 54 and 55 are tapered and spaced apart a definite distance at a point in line with the -turn-table 88. This permits only the record directly in line with the turn-table 88 to be taken from the magazine M and placed in a playing position. The records are shifted from the magazine M onto the turn-table 38 and back again to position in the magazine by a horizontal shifting carriage C which consists of a pair of curved arms 68 and 6I partly encircling a standard size record R and connected at the turn-table end with the straight portion 62. The shifting carriage C reciprocates upon a pair of horizontal guide rails 28v flxed to the upright posts 22,` 28, 24 and 25 and lthe intermediate straps 26 and 21. Lugs 63 on the curved arms 68 and 6| extend above and below the width of the guide rails 28 and with the studs 64 projecting to guide the shifting carriage C. 'I'he rear of the carriage C also has a depending lug 65 with similar studs 64 to insure against vertical shifting of the carriage C.

the lower end o`f the depending lug 65 (see Fi s. 1 and 2) a pivot pin 66 has a slot connection with the upper end of a shift lever 61, the lower end of which is pivotally mounted alg/68 on thel rear central portion of the lower frame 2 A link 69 pivotally connected at its end to the shift lever 61 is connected at its other end by a pivot pin -18 to a rocker arm 1|. The rocker arm 1I- is preferably formed of cast mteal and is of considerable width (see Fig. 15) at the bottom to form a rigid bearing for the arm von pivot pin 12. The spring 18 .allows for a slight longitudinal motion by arm 1 .upon pin 12. A pivot pin V14 slightly below pin 18 on the rocker arm 1| engages a longitudinal slot 15 on the outer end of a link 16-and the inner end of the latter is connected to a crank arm 11 on the end of the shaft 18. Referring to Figs. 1 and 2 the rocker arm 1| has the cam way 19 cast integral with it. 'I'he latter serves the purpose of engaging and disengaging the teeth 88 on the magazine M as the'shiftingcarriage carries a record to and from the turn-table T.

A curved lever 8| pivoted on the top frame at 82 extends downwardly to a curved portion pro' 5V vided with the roller 83 in contact with the camway 19 as-shown in Fig. 1. A detent plate 84 on the central portion of the curved lever 8l is directly in line with one of the teeth 88 on the movable magazine M. As the shifting carriage C takes a record from the magazine M the cam-way 19 on the rocker arm 1| is shifted to the left (see Fig. 2). The guide posts 85 serve the purpose of steadying the curved lever 8|. A spring 86 is ,attached to one ofthe guide posts 85 with its oppo- 1f site end pinned to the curved lever 8|. -The purpose of the spring 86 "is to urge lever 8| to the left soithat it will follow cam-Way where it is rockedV to the left until detent plate 84 engages one of the teeth 88 on magazine M. This insures 20 a perfect locking of the magazine in any position selected while a record is playing.

A pair of springs 81 extending from the top t0 bottom of the magazine framework 36 provide a resilient stop -for the record R when the shifter 25 carriage C returns same to its proper position in magazine M so that the holes in the record are directly in line with the vertical rods 54 and 55 (see Figs. 6 and 15). 'I'he magazine M is provided at its lower end with an inwardly extending 30 foot 88 which has a steel insert 88' resting upon the outer ends of a lifting arm 89 (see Figs. 3, 4 and 15) and a pivot 98 on the rear of the worm gear bracket 9|. A shaft 92 journalled in the bearings 98 on the lower frame 2| carries the 35 spiral cam 94 so proportioned as to give a dellnite rise to the lifting arm 89 when turned in the direction indicated by the arrow. A roller 95 on the lifting arm 89 rests on the spiral cam 94 and gives the magazine M a. definite amount of lift 40 corresponding to the space between the records R which are shown as sixteen in number. A ratchet wheel 96 is fastened at the rear of the spiral cam 94 and a pawl 91 pivoted at 98 en-V gages one of the teeth dueto the action of th. spring 99. The spiral cam 94 fastened to the ratchetswheel 96 rides free on the shaft 92 and the pawl 91 permits rotation in one direction only. Fig. 4 shows the lowest position the magazine M assumes. It will be noted that the roller 95 on the lifting arm 89 has passed from the highest position of the cam 94 through the channel |88 to the positionl shown. A bridging member |8| integral with the cam 94 has attached to its outer end the guard rail |82 which 'forms the channel |80 for the roller 95 to pass through. Since the action of spring 5| and the weight of the records R tend to counter-balance one another, the whole magazine descends from the highest point to the lowest p oint at a moderate 60 speed but to safeguard against a slight overthrow of the magazine M as the knob |98 is turned to this particularpoint the guard rail |82 is employed which extends to the point |83.' The cam 94 with the channel |88 guides the roller 95 65 Y tion would mean that the whole procedure would have to be repeated. A curved guide rod |04 is fastened to the shoe portion of the lifting arm 5@ which rides in the slot |05 in the lower frame 2|. The front side of the spiral cam 9d has the two teeth |06 cast integral with it. The latter engage a clutch |01 on the same shaft. The clutch |01 is slidably mounted on the shaft Q2 having a pin Hi8/on the shaft 92 engaging a slot |09. Referring to Figs.- and 1'1` a clutch lever ne pivotod ot m is provided with tno shifter pin Referring tongs. 3, 15 and 15A a irnos #ce on y the outside of cabinet (not shown) has latoothed end which engages a clutch member on a sprocket only when the knob `is depressed at the same t time disconnecting a circuit switch. The sprocket connects with a chain ||S (see Fig. 15) to a. sprocket HS on the shaft 92. When the clutch |01 engages the teeth |135 on the cam Sri the whole can be turned as a unit in the direction indicated by the arrow. A bent strap i2@ attached to the upper part of the magazine frame 36 terminates in a pointer |2| which is bent to appear before a program frame |22 which has the various selections |23 indicated in a manner corresponding with the arrangement of the rec.- ords in the magazine.'y By depressing the knob wt the operator can shift to any record desired, but when knob it@ is released the shaft 1Q starts to rotate, throwing the clutch lever `|||i out of the groove H1 on the flat ring |155. This action of the clutch lever Ht releases the vclutch. |01 from the teeth I on the-cam @d and as a result will not turn with the shaft 92. The cam 9d at this stage is disengaged from the shaft s2 to safeguard against any change of record while the machine is in operation. The shaft 1S is provided with a worm wheel HS driven by a worin 52 on the cross shaft |25 journalled in the worm gearv bracket 9| and at its outer end in the bearing lug |26. Shaft |25 is driven by a spring belt |28, passing on a. pulley |21 on shaft |255. and the small pulley |29 on the shaft of a motor i3d. The motor |3|i is resiliently suspended from a lug 83| cast as part of the frame 2|. Two leather strips |32 with a number of thin ilexible straps or" metal |33 are fastened to the lug |3| at the upper ends, the exible straps |33 being bent to nt the diameter of the motor and being secured thereto. It hasbeen found that in combination with a spring |28 this motor will operate successfully evenl though the pulleys |21 and I2@ are slightly ont of alignment.

Referring to Figs. 1 and 11 a cam |3li on the shaft 18 engages a roller |35 on the lower part of a raising lever |36 pivoted' at |31 on an upright lug v|38 on the lower frame 2|. The raising lever ISE has an L-shaped projection i3@ disposed above it, the opposite end of which is secured 'to the lower end of a long `vertical shifting bar Idil extending and sliding between straps MI secured to the frame. Near the center of bar |60 a. spring |42 issecured, the lower end being' .fastened at |43. The tension of the spring |62 always tends tohold ythe shifting bar |46 downward and with the .shaped projection |39 bearing downion the raising lever |36 with the roller |35 in contactwith the com |36. As shown in Fig.. 1 abracket IM is fastened to the shifting bar |535. It extends to the right and 5 has a v-shaped end M5 which bears in a groover |48 arranged on the lug 55; of the shifting carriage C. This secures 'the shifting carriage C inproper relation to the magazine M when the records R are selected. `As a record R is taken lo fromlthe magazine M the shifting bar ld@ is raised by the cam |35 and the ter' carrie C is released from the lug t5.

Extending to the center of the tumetable T is a centering arm |61 secured to the shifting bar 15 It@ and provided with-a center locating pin Md. As the record R passes to the turn-table the pin Md on the centering arm |51 is raised until properly positioned on turn-table JI. As best sho in Figs.- l' 11, 12, 13 and 14 a curved hearing 20 bracket M39 firmly secured to the upright post 2|, extends downward to form a bearing |55 and to the right to form a kbracket |56 on which a swivel collar |52 is pivoted at |53. A turning rod |54 centered in the bearing |5|i is connected with- 25 the pin |55 to auniversaljoint |55 through which a tone arm tube |51 is passed. Joint |5$ termi-1v nates at the top in an eccentric post tot clearly shown in Fig. l2. The turning rod it@ also extoncs downward in the bearing a5@ and has a 230i collar |59 with an extending rod |65 secured to operate a push switch |6| when desired.

Aseund box |62 is secured 'at the inner end of the tone arm tube .|51 and an eccentric collar |51' is disposed above a track bar |63. At the rear of the tube |51 a weight idd is fastenedto help counter-balance the tone armwhen swung to the starting position on record R. Y electric conductor itt paasses through the tone arm tube |51 from the sound box |62, to the plifier (not shown). .de lug |65 on the centering arm it? holds a pivot pin |61 on y l track bar |65 is pivoted.\'l'l1e opposite end of track bar |53 is also pivotally connected at itt to a stationary lug extending upward from the supplemental frame 35. An adjustable stop plate |69 limits the outward swing of the sound box |62 at the point of theecoentric collar |51'.

A rod Ht attached'to swivel collar |52 and extending substantially parallelto centering arm |61 passes througlirallug |1| on that arm, the pivot |53 of the swivel4 collar is so positioned that if the free end rod |19 is raised the swivel collar .will be rotated;v Asecondromdlt also projects from swivel collar iand passes `directly in iront of eccentric post |58 on universal joirtitt which carries the tone armtube (see Figs. l2 and ld). With this arrangement when ceiite.y n n Ddl `which one enti of the completed to lift the gcentering pin Hdd out of 60 engagement 'lwitli the center hole of the record, the inner end'of the track bar |63 which is pivoted Ito the centering armmis raised so that the track- 'assumes an .-outwafrdly ^sloping position down which the slide. Many/automatic phonographs dependv "en-L.

be given the necessary motion. Thcresult is that 75 the tone arm and reproducer have gained considerable momentum when' the stop plate is reached and receive a heavy jar which is detrimental t0 the delicate parts of the reproducer.

By the arrangement described above when the centering arm |41 is tilted upwardly rod |18 is also swung upwardly with the result that swivel collar |52 is turned and rod 1| swung to engage and press against eccentric pin |58. This pressure of rod |12 against pin |58 results in an outward swinging of the tone arm and recorder. Because of this positive mechanical movement the slope of track bar |68 need not be great, with the result that the speed of outward swing of the tone arm and reproducer may be very low so that when it strikes stop plate |68 its momentum will be so low that no shock detrimental to the delicate parts of the reproducer will result.

Referring to Figs. 9 and 10 a lug |18 adjusted at |18' on the supplemental frame 85 has centered at its upperend the pivot pin |14 extending toward therecord R. A groove pilot |15 swings on the pivot pin |14 and an arm |16 projecting outwardly has a counter-weight |11 adjustably xed near its end. A stop pin |18 secured in the lug |13 limits the movement of counter-weight |11. As clearly shown at Fig. 9 the sound box |62 has passed from the central part of the record R to its outer limit due to the incline of the track bar |63 and its coordinating parts. At the same time the sound box |62 contacts with a curved surface |18 on the groove pilot |15 and as the track bar |83 is lowered will correctly position the needle |88 in the starting groove of the record R (see Fig. 10).

The usual mode of operation is to depress knob |88 in the front of the cabinet. This opens a circuit switch |8| and permits the operator to select a favoriate composition from the program by turning the knob in a clockwise direction until the point |2| indicates that the record desired is in position to be shifted from the magazine to the turn-table. As long as the knob |88 is ,depressed the circuit is open. The mechanism will not function until the pressure is released and one or more coins are deposited in the coin slot |82. Conductors |81 and |88 lead from an ordinary source of electric current to a driven contact drum 284 and a change'motor |88 respectively. A branch |88 leads to the tum-table motor 32. At the time the coin is deposited the lamp |83 notifies the operator and a magnetic "circuit is closed by the coin between the conductors I 84 and |85. The magnet |86 consequently attracts the armature |81 which is provided with an escapement mechanism |88 which turns the ratchet wheel `|88 in a clockwise' direction at the rate of-one tooth for every impulselimparted'to magnet |86 by the deposit of ac'oin. A master switch 288 closes the line 28| leading to the phonograph motor 82, at the same time establishing a circuit through the lines 282, the circuit switch |8| (which is normally closed), to the contactor 283 on the drum 284. This contact drum 284 revolves with the shaft 18 and makes one complete turn for every coin deposited. 'I'he central contactor 285 is constantly in circuit on the drum 284 but the portions aligned with the contactors 283 and 286 have insulated inserts 281',

with the mechanismin motion the shifting carriage C takes a record from magazine M and deposits it on tum-table T. At the same time the centering pin |48 is lowered and the needle |88 deposited on the record. When the record starts 5 to play the change motor |38 is thrown out of circuit because the drum 284 has turned so'that the insulated insert 281 breaks the circuit of line 288. When a record has been played the sound box |62 has travelled the full distance across it. l0

` Then a pin |68 turning with the tone arm tube |51 in the bearing |58 presses against the push switch |6| again closing .the circuit through the line 288 starting the change motor |38 at which time the centering pin |48 releases the record`and 15 allows the carriage C to return the record to inagazine M. The shaft 18 has a cam arm 2|8 secured to same which as it is nearing the end of a .complete cycle, pushes the lever` 2|| to the right, the lower end having the connecting rod 20 2|2 fastened to a pawl mechanism 2 I3. 'I'his advances the ratchet wheel |98 one notch tothe left at each complete revolution of the shaft 18 or for each coin deposited. A pin 2|4 secured to the ratchet vwheel |88 is advanced toward the 25 switch ann 2|5 in successive steps until the pin 2|4 pushes the arm 2|5 downward disconnecting the master switch 288, at which time the whole mechanism is disconnected from the incoming line. 30

Referring to Figs. 1, 3 and 1l an advancing arm 2|6 secured at the shaft 18 is in direct alignment with the sprocket 86 on the shaft 92. As the shaft 18 has nearly completed a turn an insert z n on the arm 21s engages the sprocket as te ad- 35 vance same the distance of one tooth and, consequently, raising the magazine M so that the next record R is in alignment with the tum-table.
